Function async_std::fs::write

pub async fn write<P: AsRef<Path>, C: AsRef<[u8]>>(
    path: P, 
    contents: C
) -> Result<()>

Writes a slice of bytes as the new contents of a file.

This function will create a file if it does not exist, and will entirely replace its contents if it does.

This function is an async version of std::fs::write.

Errors

An error will be returned in the following situations:

• The file's parent directory does not exist.
• The current process lacks permissions to write to the file.
• Some other I/O error occurred.

Examples

use async_std::fs;

fs::write("a.txt", b"Hello world!").await?;
